UNITED STATES ALBERT R. KUNKEL, 0F PAL ESTINEITEXAS APPARATUS FOR BURNING CRUDE OIL.

Application filed May 16,

To all whom it may concern:

Be it known that I, ALBERT R. KUNKEL, a citizen of the United States, and resident of Palestine, in the county of Anderson and State of Texas, have invented certain new and useful Improven'ients in Apparatus .i'or Burning Crude Oil, of which the following is a specification.

This invention relates to means for burning crude oil and is particularly adapted or use in stoves, such as cook stoves. Its objects are to secure a thorough and complete mixture oi the crude oil and air,-an effective combustion of tl'llSdIllXllllI'G, and to secure these results in an apparatus which .is of simple constriurtion and of convenient form for handling.

With these objects in View the invention consists in the novel features which will be apparent. from the following description taken in connection with the accompanying drawing.

In the drawing,Figuro 1 is a side view partly in section showing my device in oporation; and Fig. 2 is a horizontal section through my mixing chamber and discharge nozzles.

In the drawings Ihave diagrammatically shown in section a portion of 'a'stove or furnace to which my invention is applied, that stove being provided with a floor or support 1, and a side wall 2, which may be the door of the stove. The wall=2 is provided with one ormore small perforations 3, according to the-number of discharge nozzles which are used, and directly iniront of'these openings I place a splash plate 4 in vertical -posi tion so that when a r'hixture of oil and air is discharged through these openingsdt willbe directed toward the splash plate. The splash plate is carried by supports flwhich may be made of metal or other refractory material with enlarged weighted lower ends 6 which serve to balance and hold in position the s lash late. These supports rest in a s las pan which in turn rests either upon t e floor of the stove, as shown in Fig. 1, or upon the grate bars.

In order to supply the combustible material directed against the splash late I make use of the mixing chamber and dischargenozzles coi'istituting the burner shown in Fig. The mixing chamber 8 is made elongated and preferably in tubular form, having in one end the screw plug i; provided with the Specification of Letters Patent.

central discharge nozzle 10 for su plying air underprcssure to the mixing c amber. The opposite end of the mixing chamber is closed by a removable screw plug 11 and immediately adjacent the air inlet nozzle 10 I provide an inlet nozzle 12 for the crude oil under pressure, and this last mentioned nozzle discharges across the air inlet at an angle preferably in a diagonal direction, so that the oil will move across the air which is discharged into the mixing chamber. This mixing chamber is provided with any suitable number of lateral nozzles 13, 14 having small discharge outlets, and. those nozzles are provided with needle valves 15 and 16, passing across the mixin r chamber and held in position by screw tlireaded connection with bosses 17, 18. Theseneedle valves are provided with the usual hand wheels for op crating vthem, and the usual packing joints to prevent leakage.

'In order to supply the air and crude oil under pressure to the, mixing chamber I makeuse of a tank 19 so constructed as to retain air under pressure, and an oil outlet.

"leading to the burner and this connection 22 is provided'with a valve, There is also a valved inlet connection 24 through which the air under ressuremay be introduced into the tank rom' an air pump or other source of supply, and the device may be provided with a pressure indicator 24. The

air pipe 23 has an atomizer valve 26 immediately adjacent the point Where this pipe connects with the inlet nozzle 10 of the mixing chamber so that't-he operator may control the action of the an in the mixing chamber. The pipe 27 conveys the crude oil under pressure from the tank to the discharge nozzle 12, and since the oil and air are both under the same pressure and are discharged by the compressed air lon 'tudinally of the mixing chamber there W1 1 be a thorough mixing of the... oil and air and the I two will pass together out of-the nozzles 13' and 1.4 as a combustible migture. The mixture in passing through the openings flwill draw in more an, and thus thena-Wil thorough combustions within the' stove it and surrounding the splash plate 4. If any particles of oil strike the splash plate they will fall to the splash pan 7 i and w ll there 'burn.

It will be observed that my pressure tank as wellas the mixing chamber ,and burnersare of convenient form for removal and that they may be a plied to an ordinary stove as distinguishecffrom large furnaces requiring great heat and considerable room for the combustion. As'sh'ow in the drawings, my burner may be inounte "*on'the door or side wall of a stove by means of aubracket or other suitable means-of connection. .I have shown a bracket 28 conn'ected to the mixing chamber and vsupported at its lower end uponna rod -or bracket 29 which is passed .t-hron-gl'i the-wall of the stove and secured in place by nuts. A screw 30 may be used for -g=1ving. an adjustable connection between the bracket 20 and the arm 29 so that the position of the dischargenozzles 13 and 14 with reference to the openings 3 may be regulated;

Having thus described the invention, What 1. In a device of the class described, the

combination with a stove, the wall of which is provided with a burner openin of a splash plate within said stove in rout of said opening, supports for said plate having enlarged we] hted lower ends, a splash pan in which said su ports rest, a mixing chamher for crude oil and air supported on said wall, a nozzle commnnicatin with said chamber and disehargin t'irough said opening against said sp ash plate,""and means for supplying oiljand air under pressure to said mixing chamber.

2. A crude oil burner comprising an elon gated tubular mixing chamber, a nozzle for compressed air discharging into said cham her at one 'end, a nozzle for crude oil under pressure discharging across said air inlet, ischarge nozzles for the mixed airand oil leadingdaterally from said. chamber, and needle valves in said nozzles.

In testimony whereof I afiix my signature in presence of two witnesses.
